Nowadays, plenty of heterogeneous catalytic processesapplied in industry are based on utilization of nanoparticles of catalytically active materialsfixed on the various porous structures. Application of graphene and related compounds ascatalysts for facilitating synthetic reactions is a relatively new area of research withoutstanding potential. The unique properties of well-defined 2D nanomaterials, such asgraphene and graphene oxide are suitable for facilitating of a wide range of reactions and mayoffer new routes in the design of novel catalytic systems. For example, platinum andpalladium nanoparticles immobilized on the surface of graphene oxide were used in theelectrooxidation of methanol and the hydrogenation of alkynes [1], and palladiumnanoparticles on the surface of graphene oxide have shown high efficiency in cross-couplingreaction of phenylboronic acid with aryl bromides and iodides [2]. However, in most ofexperiments, expensive precursors had to be used or synthetic procedure requires long time.In this paper, nanoparticles of noble metals (Au, Pd, Rh, etc.) on the surface of graphene andgraphene oxide have been obtained. As a precursor for the synthesis of nanoparticles, salts ofthe suitable metals have been used. The resulting nanocomposites were characterized bymethods of physicochemical analysis and then tested as catalysts for organic reactions (crosscouplingreaction, formylation, etc.). High degree of conversion of organic reactions withnoble metal nanoparticles on the surface of graphene oxide and graphene used as catalysts hasbeen demonstrated in these studies.References[1] H.-W.
